As shown in FIG. 5, the bag body 2 in which a certain amount of rice is packed from the hopper 1 is carried to the sewing machine 4 by the belt conveyor 3, and the mouth 21 of the bag body 2 is sewn in the sewing machine 4 by the handling conveyor 5 Sent to. The bags 2 sent to the handling conveyor 5 are picked up and stacked on a pallet 8 so as to be held by a hand 7 provided on the bag handling robot 6 and provided with gripping claws 71 that can be opened and closed.

すること目的とするものである。However, in the above configuration, the mouth 21 of the bag body 2 is closed by the sewing machine 4 in the upward state, and thus the bag body 2 is inflated downward, and the bag body 2 is collapsed by this downward inflation. It is conveyed to the handling conveyor 5. When the bags 2 in the downwardly bulged state are stacked in multiple stages on the pallet 8 by the hand 7, as shown in FIG. 6 (a), the upper part of the stacked stages is greatly inclined or the stacking height becomes high. It becomes difficult to stack in multiple stages. There is also a method in which the bag mouths are stacked with their mouths turned in different directions, and the upper surface of the stacks is made almost horizontal as shown in FIG. 6 (b). It had to be rotated 180 degrees each time it was gripped, which was a disadvantage that it took a lot of time. An object of the present invention is to make the upper surface of the bag flat so that it can be stacked in multiple stages.

The upper surface of the bag body is formed flat. In this way, if the bags with a flat top surface are lifted by the gripping claws and stacked on a pallet, etc., the top surface of the bags will have the same flat surface from the first stack to the top stacked in multiple stages, and thus the stack can be stacked in multiple stages. It will be easy.

1 is a side view showing an embodiment of the present invention, FIG. 2 is a front view,
In the hand 7 of the bag handling robot 6, a middle portion is pin-connected to a base portion 72, one end is connected to a cylinder 73 capable of reciprocating motion so as to be opened and closed, and a grip claw 71 divided into a plurality of pieces is provided. It is provided. The other end of the grip claw 71 is formed in a key shape so that the bag body 2 is lifted when the grip claw 71 is closed. The grip claws 71 have the same spacing between the tips of the adjacent grip claws 71 as the roller 51 so as not to interfere with the rollers 51 of the handling conveyor 5. Below the base portion 72, a plurality of pressing rollers 74 that rotate in a direction perpendicular to the opening / closing direction of the grip claw 71 and that are arranged in the same direction as the direction in which the grip claw 71 is divided are provided. When the bag body 2 sent to the handling conveyor 5 is lifted by the grip claws 71 of the hand 7, first, as shown in FIG.
Further, as indicated by a solid line in FIG. 4, the hand 7 is moved above the bag body 2 in the inflated state with the grip claw 71 open. From this state, as shown in FIGS. 1 and 2, the hand 7 is lowered to press the pressing roller 74 against the upper surface of the bag body 2. While pressing the pressing roller 74 against the upper surface of the bag body 2, the hand 7 is reciprocated in the rotation direction of the pressing roller 74 to flatten the upper surface of the bag body 2.
Next, the hand 7 is lifted up, and the grip claw 71 is closed by the cylinder 73 as shown by the alternate long and short dash line in FIG. 3 to hold the bag body 2 having a flat upper surface and move the hand 7 to stack it on the pallet. take down. Although the above description has been provided with the divided gripping claw and a plurality of pressing rollers, the gripping claw does not change the flat shape of the bag body and does not interfere with other equipment such as a handling conveyor. If it is present, it need not be divided, and the pressing roller need not be plural.

と共に、作業時間が短縮される効果がある。As described above, according to the present invention, the pressing roller is provided on the hand, and the upper surface of the bag body is pressed by the pressing roller before the bag body such as the bag body is lifted by the gripping claws provided on the hand. Since it is formed flat, the top surface of the bag body is the same height from the first stage to the upper part where multiple layers are stacked when gripping with a gripping claw and stacking on a pallet, etc.
In addition, it has a flat shape, which facilitates stacking in multiple stages and has an effect of shortening the working time.
